Fluidwell F114 Ratio Monitor and Totalizer
Overview
The Fluidwell F114 Ratio Monitor and Totalizer is a field-mount flow computer designed to calculate the actual ratio between two separate flow streams, with independently configurable low-ratio and high-ratio alarm values. Built for mixing, blending, and dosing applications where maintaining a precise proportion between two components is critical, the F114 displays ratio, alarm status, flow rate A and B, and total A and B, with the ratio presentable either as 1:__ notation or as a percentage.
Seven Star LLC supplies the Fluidwell F114 as an authorized partner to blending, coating, and process facilities across Oman and the GCC. Every unit shipped through Seven Star LLC is genuine Fluidwell equipment with full manufacturer warranty, correct hazardous-area certification, and local applications support for installations in Muscat, Sohar, and Salalah.
Measurement and Operating Principle
The F114 accepts pulse-type inputs from two independent flowmeters – reed-switch, NAMUR, NPN/PNP pulse, sine wave (coil), or active pulse signal – with different pulse signal types permitted on input A and B simultaneously. Based on the relative location of the two flowmeters in the process, the F114 offers a selection of six different ratio calculation formulas, ensuring the displayed ratio accurately reflects the physical measurement arrangement. Special start-up precautions prevent false ratio-alarm triggering during transient flow conditions.
Configurable alarm outputs – up to three, available as passive NPN transistors, active PNP transistors, or isolated electro-mechanical relays – can be set for low ratio, high ratio, or both conditions combined, with clear on-screen alarm messages. An analog output re-transmits the actual ratio or either flow rate, scalable to any range required by the downstream control system, available as passive isolated 4-20mA, active (0)4-20mA, or 0-10V DC.
Engineering Design of the Fluidwell F114
The F114 is housed in a robust aluminum or 316L stainless steel field enclosure rated IP65/IP67 (NEMA Type 4X), engineered to withstand harsh weather conditions including rain, snow, sandy desert environments, and salty coastal atmospheres common across Oman’s industrial regions. The enclosure operates reliably across an ambient temperature range of -40°C to +70°C, and settings plus running totals are automatically backed up in EEPROM memory to protect against data loss during power interruption.
Intrinsically safe variants are ATEX and IECEx certified for both gas (Ex ia IIB/IIC T4 Ga) and dust (Ex ia IIIC T200 100°C Da) hazardous locations, while explosion-proof variants offer Ex db IIB+H2 T5 Gb gas and Ex tb IIIC T80°C Db dust protection. Communication is via Modbus RTU over RS232, RS485 (2-wire or 4-wire), or TTL interface, with all process data and configuration settings readable and adjustable through the communication link.

Industrial Applications
The F114 is widely used in mixing and blending processes across Oman where continuous ratio display, monitoring, and totalizing of two components is essential, including construction material dosing, roof and wall insulation coating processes, gluing operations, and chemical blending. Its rugged, weatherproof enclosure design and wide ambient temperature range make it well suited to outdoor installations exposed to Oman’s high summer temperatures and Sohar’s coastal salt-laden atmosphere.
As an authorized Fluidwell partner, Seven Star LLC supports industrial and construction material producers across Muscat, Sohar, and Salalah with genuine F114 units correctly configured for the target hazardous-area classification and flowmeter pairing. This authorized-partner relationship ensures dosing and blending accuracy is backed by manufacturer warranty and responsive local technical support.

Why Choose Seven Star LLC for Fluidwell Batch and Ratio Control Instruments
A ratio monitor and totalizer only performs correctly when its input signal type, hazardous-area certification, and control output configuration genuinely match your blending or dosing skid, since a mismatched input range silently skews the ratio calculation without triggering an obvious fault. Seven Star LLC confirms the correct F114 configuration against your actual blending process and flow meter signal types before shipment, backed by our authorized Fluidwell partnership across Oman and the wider GCC. We also support chemical dosing and fuel blending operators across Sohar and Salalah with panel integration guidance, helping ensure the totalizer’s outputs interface cleanly with existing PLC or SCADA-based batch control systems.
Contact Seven Star LLC today to order the genuine Fluidwell F114 Ratio Monitor and Totalizer with full manufacturer warranty, correctly specified hazardous-area certification, and expert technical support for blending and dosing projects across Oman and the GCC.
